Title: High pressure steam producer - burns hydrogen with oxygen under water in a closed pressure vessel
Inventor: FRIES GUSTAV
IPC: F01K25/00
Filed: 1975-03-19
Abstract: A closed pressure vessel (1) is surrounded by an insulating jacket (9) and contains water to a certain level (11). Hydrogen is supplied through a reducing valve (5) from a cylinder (7) to a burner nozzle (2) below the water level. Oxygen is supplied to the nozzle from a cylinder (8) through a reducing valve (6). The heat of the flame produces steam at high pressure (12) above the water level in the vessel. The steam flows past a stop valve (14) through a control valve (15) to a steam turbine (16) or steam engine. The exhaust steam is condensed (17) and collected in a hot well from which water is pumped back into the vessel (1). Combustion within a closed vessel with the production of water ensures that no harmful combustion products escape to atmosphere.

Title: Hard metal on titanium carbide base - non-stoichiometric compsn. with niobium stabilisation
Inventor: DZODZIEV GEORGIJ T
IPC: C22C29/10
Filed: 1977-03-16
Abstract: The hard metal contains Ti carbide of compsn. TiC0.85-TiC0.94 stabilised by 0.05-0.10 wt.% Nb as well as 10-30 wt.% Ni and 2-5 wt.% Mo. Microalloying with Nb provides a uniformity in bending strength of th ehard metal unobtainable so far. The components are ground by a wet process, dried, pressed and sintered in a vacuum. Conventional hard metals show a large scatter in the strength properties, in particular the bending strength (15-20%), so that the reject rate is high and the service life often short. Microalloying with Nb consistently gives high bending strength values. Nb levels below 0.05 wt.% have no effect and content above 0.10 wt.% do not increase the stabilisation effect. A higher C content than TiC0.94 (19% C) does not raise the strength of the hard metal any more, wh ile one below TiC0.85 (17.6% C) considerably lowers the strength and cutting properties.
